Summary
Long non-coding RNA AFAP1-AS1 promotes osteosarcoma progression by regulating the miR-497/IGF1R pathway. Inhibiting AFAP1-AS1 suppressed tumor growth and metastasis, suggesting it as a potential therapeutic target for osteosarcoma.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- Long non-coding RNAs (lncRNAs) are implicated in cancer progression.
- The specific role of AFAP1-AS1 in osteosarcoma (OS) is not well understood.
Purpose of the Study:
- To investigate the function and regulatory mechanisms of AFAP1-AS1 in osteosarcoma.
- To explore AFAP1-AS1 as a potential therapeutic target for OS.
Main Methods:
- Quantitative real-time PCR (qRT-PCR) to assess AFAP1-AS1 expression.
- Loss-of-function experiments (knockdown) to evaluate AFAP1-AS1's role in OS cell behavior.
- Bioinformatics analysis, luciferase reporter assays, and rescue experiments to elucidate the regulatory pathway.
- In vivo xenograft tumor assay to assess therapeutic potential.
Main Results:
- AFAP1-AS1 was significantly upregulated in OS tissues and cell lines, correlating with poor prognosis.
- Knockdown of AFAP1-AS1 inhibited OS cell proliferation, colony formation, migration, and invasion, while inducing apoptosis.
- AFAP1-AS1 directly targets miR-497, and this interaction influences the expression of IGF1R.
- AFAP1-AS1 knockdown suppressed tumor growth in vivo.
Conclusions:
- AFAP1-AS1 promotes osteosarcoma progression through the regulation of the miR-497/IGF1R axis.
- AFAP1-AS1 represents a promising therapeutic target for osteosarcoma treatment.

9.6K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

4.5K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

3.6K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

5.0K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
